OPKs on CD0 (question) (tmi)

[Dill]

Ok, so you ladies know I had my Mirena IUD removed earlier this month, post-ovulation. I had several days of spotting (mostly a few brown streaks in my cm and some tissue I think), but my temps remained elevated. AF isn't due yet, but I had a big temp drop today, and more spotting that I counted as light flow (slightly heavier brown streaking and more tissue bits). I have a POAS problem, and on a whim, took an opk and hpt at lunch. The hpt was negative, of course, but the opk was pretty strong - it's been nearly stark white, just a vvvfl since I ovulated. I know fluctuation is normal, but I wouldn't ordinarily see this strong of a line until the week of ovulation. That said, I've never used one during AF, so I don't know if that might be normal. I guess I'm wondering if I should keep doing OPKs in case I may ovulate early in this cycle due to the IUD removal weirdness?
